Drop block
A drop block (analogous to, and sometimes called, a Donut Lift from the Mario series) is a certain type of platform usable in the Stage Builder of Super Smash Bros. Brawl. In Stage Builder, they are brown blocks with dark brown upside-down triangles on the sides. When stepped on for long enough by characters or items, these blocks shake, then fall. They eventually reappear. They only drop when they are stood on, so it is possible to make one-way passages by sealing a narrow entry with a drop block. Interestingly, it is possible to wall cling to the side of a drop block without making it fall.
Drop blocks also appear in certain levels of Adventure Mode: The Subspace Emissary. These drop blocks fall faster and are usually placed over a gap, spikes, or water and between a character and a target. These drop blocks do not reappear (except in Subspace I, where they cover an extended area without ground), so careful planning (or a floaty character) are required to avoid having to replay the stage.
There is a glitch, known as the Flop Block, associated with them. Another glitch occurred with this block is the Teleport glitch.
Trivia:
- When used on custom stages, drop blocks are able to fall right through characters and other platforms.
